Identification by Raman microscopy of anachronistic pigments on a purported Chagall nude: conservation consequences

Tracey D. Chaplin, Robin J. H. Clark

Applied Physics A > 2016 > 122 > 3 > 1-5

A painting purported to be by the artist Marc Chagall has been examined using Raman microscopy to check on its proposed execution date of 1910. The analysis shows that, due the presence of phthalocyanine pigments, the painting cannot have been created prior to c.1938. Transport of the painting to the Chagall Committee in France for inspection has led to their declaration that the painting is a forgery...

Characterization of an iron smelting slag from Zimbabwe by Raman microscopy and electron beam analysis

Vânia S. F. Muralha, Thilo Rehren, Robin J. H. Clark

Journal of Raman Spectroscopy > 42 > 12 > 2077 - 2084

This pilot study aims to develop a model that allows close identification of the redox conditions in a variety of smelting processes by analysing the free iron oxides. Characterisation by RM and EBA of archaeological iron smelting slag from Northern Zimbabwe reveals free iron oxides, as haematite and magnetite, oxidised forms of magnetite and wüstite, Al³⁺‐substituted magnetite and a solid solution...

Rutherford and Raman – Nobel laureates who had difficult early journeys to success

Matthew P. A. Clark, Robin J. H. Clark

Journal of Raman Spectroscopy > 42 > 12 > 2173 - 2178

Two remarkable men, Ernest Rutherford in New Zealand and Chandrasekhara Raman in India, had very demanding early backgrounds from which most would fail to emerge with distinction. Yet, each rose to the top in science, Rutherford being awarded the Nobel Prize in Chemistry in 1908 and Raman the Nobel Prize in Physics in 1930. Their fascinating lives overlapped in interesting ways. There were many hurdles...

Spectroscopy study of mural paintings from the Pyrenean Church of Saint Eulàlia of Unha

Journal of Raman Spectroscopy > 41 > 11 > 1418 - 1424

A series of wall paintings dating from the Romanesque period to the 16th century were uncovered during restoration projects at the church of Santa Eulàlia of Unha in the Val d'Aran. This study centres on the use of complementary spectroscopic techniques to examine comprehensively the pigments, binders and other materials associated with these mural paintings. These include Raman microscopy, far and...

Far‐infrared spectroscopy, the wavenumbers of metal–ligand vibrations and the characterisation of inorganic pigments

Robin J. H. Clark

Journal of Raman Spectroscopy > 41 > 4 > 361 - 362

Extensive far‐infrared studies of inorganic materials and pigments in the early 1960s are highlighted and related to the many subsequent Raman studies of the same materials, studies which led to the formulation of Raman spectral libraries for use in conservation science. The need for complementary infrared/far‐infrared libraries is recognised. Copyright © 2010 John Wiley & Sons, Ltd.

Laser-induced degradation of lead pigments with reference to Botticelli's Trionfo d'Amore

Gregory D. Smith, Lucia Burgio, Steven Firth, Robin J. H. Clark

Analytica Chimica Acta > 2001 > 440 > 2 > 185-188

The recent analysis of the palette used in Botticelli's Trionfo d'Amore by Raman microscopy has led to the erroneous identification of the spectrum of a degradation product, most likely that of massicot (orthorhombic PbO), as that of plattnerite (PbO ₂ ) [Anal. Chim. Acta 429 (2001) 279]. The error is shown to arise from the laser-induced degradation of both the painting and a reference sample...
